COUPLER -RELEASE RIGGING.

Application filed April 6,

To all'wiwm it may concern:

Be it known that I, STERLING H.- CAM]?- BELL, a citizen of the UnitedStates of America, residing at thecity of St. Louis, State of Missouri,United States of America, have invented a certain new and usefulCoupler-Release Rigging, of which the fol lowing is such a full, clear,and exact description as will enable anyone skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings forming part of this specification.

My invention relates to a coupler release rigging and has for its objectthe construction of such a device which will be simple in form andeffective in operation and which may be either applied to operating rodsof the type now in use or to a specially constructed operating rod.

In the accompanying drawings which illustrate some forms of devices madein accordance withmy invention together with a portion of a railway car.to which the same is applied, Figure 1 is a top plan view, Figure 2 isan enlarged section taken on the line 2-2 of Figure 1. Figure 3 is a topplan viewof the end of the operating rod and attached parts, Figure atis'a-front view of the parts shown in Figure 3, Figure 5 is a sideelevation of the parts shown in Figures 3 and 4. Figures 6 and 7 are atop view and vertical section, respectively, showing a modificatiom.andFigures 8 and 9 are a vertical section and top plane view, respectively,showing a still further modificatlOD. 1

10 indicates the end of a railway car carrying a coupler head 11provided with the usual locking pin 12 having a horizontal eye 13. 14 isan operating rod provided with a handle 15 and carried in brackets 16and 17 respectively. The bracket 16 is formed of a strip of metalsecured to the car '10 by means of rivets18 as shown in Figure 2 andprovided with a, downwardly and forwardly extending bend 19 adapted toreceive the rod 14:. This bend 19 is preferably arranged at entangle ofabout The rod 14: is held in position in the bend 19 by means of acotterpin 20. Owing to the shape of the bracket 16 there will be butlittlepressure against the cotter pin 20 as the movement of theoperating rod in lifting the locking pin, of the coupler will tend tomove the rod forward against the closed 1921, Serial no. 458,888.

portion of the bend 19. The bracket l'l' may be of the same form as thebracket 14- or it may be any other suitable form such as is now used.

In carrying out my invention, 1 the forwardly projecting arm 21 of theoperating rod is provided with'a non-cylindrical ver tical eye. In theform of my device shown in Figures 1 to 5, inclusive, this, eye isformedin an integral portion 22 of the arm 21, th'eportion beingprovided by flattening i Y the end of the rod. -The opening '23 in thisflattenedportion 22 of the arm. is of con-. I siderably greater lengththan width as best shown in Figure 3 of the drawings. To connect the arm21 with the coupler locking pin 12, I provide a stirrup I24 consist-.ingof apair of parallel bars 25 connected at their lowerends by aflattened'portion-26 forming a'n elongated loop. Ea'chofthe bars 25 isprovided atfits upper eridwith an outwardly extending portion '27.: Thedistance between thetwo bars25 is ,suflicient to allow the stirrup to bepassed' through the eye 13 of the locking pin 12' and their outsidedimension is suflicientto allow them to easily pass throughthe verticaleye 23 of the operating rod when in the position ;shown"in Figure 3. Inplacing the arm 21 in engagement with the stir the operating rod' 14' issecured to the car 10, the rod'is turned to a position at right anglestoitsnormal or operating position and inclined as shown in dotted lines inFigure 4 so that its longest dimension maybe engaged with the head ofthe stirrup as indicated in this figure after which the rod ru-p 24%,which mustbe accomplished before gagement of the stirrup from the eye23.

The elongated loop formed at. the' lower end of the stirrup will allowof the neces- I sary lateral movement between the coupler and operatingarm, and the necessary longltudinal movement 1s secured by the pivotalmovement of the stirrup in the eye 13;

of the locking pin and in the eye 23 of the operating rod.

In Figures 6 and 7, I have shown a modification of my device in whichthe operating rod 21 is provided with aihorizontal openattached to therod '21. I V

is provided with a cross piece adapted to engage with the upper side ofthe rod ing 30. .In this, construction a (casting having" an opening 23therein, similar to the opening 23 hereinhe'fore described, is Thiscasting 3 1 and cross piece 33 adapted to engage with the lower sidethereof. This distance between the cross piece 82 and 83 is'suilicientto allow the flattened end of the rod 21 to v pass btween them in vaninclined direction', attei' which-it is SWdllglIltO the 'position shownin Figure 7 and sccuredhy means of a locking boltifie passing throughthe sides of the casingfil and extending underthe.
